I was changing from 24P (D7000) to YouTube 720P. Funny thing is after I process it to out put in Avid Studio at the same 720P settings Vegas imports it perfectly. I tried 1080i and the same thing happens.

Ok, I've found the problem. I use three cameras, A Canon HF100, Olympus E-PL1, and and Nikon D7000. CS6 handles the 720 files from these cameras and the 1080I from the HF100 properly. It handles the 1920 files from the D7000 differently. When I try to output to Youtube 720 using the 1080P (B frame 1920 x 1080) files that's what causes Vegas to crash. When I just re-output to the same HD (1920 x 1080, 24 frames) Vegas opens the files. I don't know why "Avid Studio opens the 720 files that are down res from the D7000" but at this point in time my work around is to just change what I want to in CS6 at the 1080 P from the D7000 and re-res it in Vegas.

I’ve narrowed down the issue to the 1080P 24 frames from the Nikon D7000. When I render a Nikon 1080P 24 frame file (I use files that are 20 seconds long to test) to an MP4 file in Photoshop that is where the problem lies. Taking those files and importing them into Vegas Movie Studio HD 11 (build 322) crashes Vegas. I can import those files into avid studio and then import them into vegas with no problem. If I output the same file again in photoshop as a quicktime HD they import into Vegas perfectly. The problem must be in the way the Nikon 1080 P 24 FPS files are changed in photoshop when rendered out of photoshop as an MP4 (either as 1080 or 720). The 720 P files from the Nikon render fine in Photoshop and import correctly into Vegas.

My guess is that the 1080P 24 FPS from the Nikon use a “B” frame encoding and somehow the rendering in Photoshop does something that Vegas doesn’t like. It’s funny that Avid Studio (which I don’t use often) recognizes the 1080P 24 FPS rendered in Photoshop as MP4 (either as 720P or 1080P) fine. I don’t know if this issue appears in Vegas PRO but if so I think its an issue you might want to explore.

I guess you can change my user name to D7K, don’t know why when I changed it in my profile it did not show on the posts new to this thread.
